The 1963 Italian general election was held on Sunday April 28. It was the first election with a fixed number of MPs to be elected, as decided by the second Constitutional Reform in February 1963. It was also the first election which saw the Secretary of Christian Democracy to refuse the office of Prime Minister after the vote, at least for six months, preferring to provisionally maintain his more influent post at the head of the party: this fact confirmed the transformation of Italian political system into a particracy, the secretaries of the parties having become more powerful than the Parliament and the Government.

The Italian Social Movement was a neo-fascist political party in Italy. A far-right party, it presented itself until the 1990s as the defender of Italian fascism's legacy, and later moved towards national conservatism. In 1972, the Italian Democratic Party of Monarchist Unity was merged into the MSI and the party's official name was changed to Italian Social Movement – National Right.
